FIG. 4 is a flowchart illustrating the media file management method for the home media center according to the present invention. In a first step S10, a relevant application is driven, based on the menu selected by the user. At step S20, it is determined whether an editing operation is to be performed. If such an editing operation is to be performed, then at step S30, the screen is divided into a search window and an edit window.

Next in the simultaneous steps of S40 and S50, the media files to be searched are displayed in the search window (step S40), and the media file to be edited is displayed in the edit window (step S50). At step S60, it is determined whether a file edit command has been selected. If a file edit command has been selected, then the method proceeds to step S70, in which the selected file edit command is executed. After step S70, the results of the execution of the file edit command are displayed in the search window and/or the edit window, as step S80.

The specific file edit commands with respect to the foregoing are discussed herein. However other related art file commands may also be used, such that the present invention is not limited thereto.

If the user selects any one of the home media menus such as images or photos, music and movies by using the input device 200 (refer to FIG. 3), the media file management unit 330 drives the relevant application according to the menu selected by the user, and searches for media files according to the menu selected by the user in the home media center 100 or the plurality of information appliances S₁, S₂, . . . , S_(n). The media file management unit 330 then causes the searched media files to be displayed on the screen of the display apparatus connected to the home media center 100.

Here, the application may vary according to the menu (the kind of media file) selected by the user. For example, an image application with an image viewer function is driven in a case where the user selects the “Image (Photo)” menu, an audio application with a music playing function in a case where the user selects the “Music” menu, and a movie application with a movie playing function in a case where the user selects the “Movie” menu.

Then, the media file management unit 330 manages the media files included in the home media center 100 or other information appliances S₁, S₂, . . . , S_(n) through the applications. Hereinafter, a method of managing image files stored in the home media center 100 will be described by way of example in the present embodiment.

FIG. 5 is a view showing a screen configuration of the image application for implementing the present invention. If the user selects the “Image (Photo)” menu among the home media menus (refer to FIG. 3), the media file management unit 330 drives the image application and simultaneously searches for image files among media files stored in the memory unit 320 and then causes the searched image files to be displayed on the screen of the display apparatus connected to the home media center 100 (S10).

At this time, individual image files or album files including a plurality of image files are displayed on the screen of the display unit. The user can search the individual image files or album files using the direction buttons of the input device 200. As for a method of indicating a currently searched file, related art methods such as highlighting already searched files can be used. Therefore, a detailed description thereof will be omitted herein.

In the meantime, if the user selects a specific information appliance in an external appliance select menu M on the image application in a state where the image application is executed as shown in FIG. 5, the media file management unit 330 can search for image files included in the information appliance selected among the plurality of information appliances S₁, S₂, . . . , S_(n) connected to one another through the home network and cause the searched image files to be displayed on the screen of the display apparatus connected to the home media center 100. In this case, the media file management unit 330 may directly manage the media files included in the information appliances S₁, S₂, . . . , S_(n), or store the media files in the memory unit 320 of the home media center 100, and then manage the stored media files.

Further, the media file management unit 330 causes the full file path of the media file selected by the user through the image application to be displayed on the screen. If the full file path is too long, it may be abbreviated and then displayed in the same manner as “C:/screen.../MOMA..> 1.jpg.”

Meanwhile, as shown in FIG. 5, if the user presses the menu button of the input device 200 in a state where an image file is selected, the media file management unit 330 causes menu A consisting of “Slide Show,” “Copy,” “New Album,” “Sort,” “Select All,” “Move,” “Rename,” and “Delete” functions to be displayed on the screen. If the user presses the menu button of the input device 200 in a state where an album file containing a plurality of image files is selected, the media file management unit 330 causes menu B consisting of “Edit Album,” “Copy,” “Move,” “New Album,” “Rename,” “Sort,” and “Delete” functions to be displayed on the screen. The menu configuration is not limited to the details described above. It will be apparent that other menus may be added or eliminated, if necessary. Since the functions of the respective menus are substantially identical with those used in Windows for PCs, a detailed description thereof will be omitted.

Hereinafter, a media file editing method based on the image application will be described with reference to FIGS. 6 to 10. As described above in the related art, when the user wants to edit a media file on a TV screen by using a remote control, there are problems in that it is inconvenient to search files and difficult to edit the files.

To this end, the media file management unit 330 in this exemplary, non-limiting embodiment of the present invention divides the screen upon editing a file so that files to be searched and a file to be edited are simultaneously controlled. Thus, a file edit command selected by the user can be immediately executed. Hereinafter, the file edit operations of the media file management unit 330 will be described in greater detail.

If the user selects the “Edit Album” function in menu B (refer to FIG. 5) by using the direction buttons of the input device 200 (S20 of FIG. 4), the media file management unit 330 divides the screen into the search window D and the edit window E as shown in FIG. 6 (S30 of FIG. 4). Media files that the user wants to search are displayed in the search window D (S40 of FIG. 4), whereas a media file that the user want to edit is displayed in the edit window E (S50 of FIG. 4).

At this time, if the user selects the menu button of the input device 200 in a state where a file selection locator (focus) exists in the search window D, the media file management unit 330 causes menu F consisting of “Select All,” “Copy,” “Move,” “Close,” functions and the like to be displayed on the screen, as shown in FIG. 6 (a).

Alternatively, if the user selects the menu button of the input device 200 in a state where the file selection locator exists in the edit window E, the media file management unit 330 causes menu G consisting of “Select All,” “Copy,” “Move,” “Delete,” “Close,” functions and the like to be displayed on the screen, as shown in FIG. 6 (b).

If the user selects any one of these functions by manipulating the direction buttons of the input device 200 (S60 of FIG. 4), the media file management unit 330 immediately executes a file edit command according to the selected function and causes results of the execution of the file edit command to be displayed in the search window D or edit window E (S70 and S80 of FIG. 4). This will be described in more detail below.

When the user selects a single image file in the search window D and then selects the “Copy” function as shown in FIG. 7 (a), the media file management unit 330 immediately copies the relevant image file into the edit window E as shown in FIG. 7 (b).

Alternatively, when the user selects a single image file in the search window D and then selects the “Move” function as shown in FIG. 8 (a), the media file management unit 330 immediately moves the relevant image file into the edit window E as shown in FIG. 8 (b).

Third, in a case where the user selects a single image file in the edit window E and then selects the “Delete” function as shown in FIG. 9 (a), the media file management unit 330 immediately deletes the relevant image file from the edit window E as shown in FIG. 9 (b).

Further, the media file management unit 330 may cause a current processing rate to be displayed on the screen upon execution of the file edit command, or a message “A file with the same name already exists” to be displayed on the screen if an image file with the same file name already exists upon copying or moving an image file.

The display of the results of the execution of the file edit command for the file selected in the search window D in the edit window E has been described. However, when the user selects a file edit command for a file displayed in the edit window E, it is also possible to cause the results of the execution of the file edit command to be displayed in the search window D.

Referring again to FIG. 5, if the user selects the “New Album” function in menu A or B by manipulating the buttons of the input device 200, an image file can be added to or deleted from a newly created album by the aforementioned screen division method. In this case, the newly created album is displayed in the edit window E as shown in FIGS. 10( a) and 10(b).

At this time, a file name of the newly created album can be automatically created. For example, the file name can be created based on the creation date of the new album in the same manner as “2002-07-05.” Alternatively, if an album file created on the same date already exists, the file name can be created by using a method of adding a number after the creation date of the album file in the same manner as “2002-08-01-1”, or “2002-08-01-2”.

Meanwhile, if the user selects any one of the direction buttons of the input device 200, the media file management unit 330 causes the selection locator to move in up and down and right and left directions according to the selected direction button so that media files contained in a current folder can be searched as shown in FIGS. 11 (a) to (d).

Further, if the user selects the OK button of the input device 200, the media file management unit 330 causes a selected image file to be magnified and displayed on the screen as shown in FIG. 12 (a), or image files contained in an album file to be displayed on the screen as shown in FIG. 12 (b). In this case, the image application can perform operations of rotating or deleting a currently selected image file, and the like.

The foregoing steps of the presently claimed invention may also be implemented in a computer readable medium of any type. Computer readable mediums are well-known in the art, and may include disk drive, remote storage, wireless storage, and portable storage. The computer readable medium stores the steps as a set of instructions that may be implemented.

The present invention has various advantages. For example, but not by way of limitation, according to the present invention described above, the user can easily edit and manage media files such as images or photos, music and movies, which have been received from PCs, DVDs, camcorders, digital cameras and the like, on the screen of the display apparatus connected to the home media center, simply by manipulating the remote control.

Therefore, according to present invention, the user can easily edit and manage media files on the screen of the display apparatus connected to the home media center only by means of simple manipulations of the remote control.

Further, according to the present invention, since the media contents stored in other information appliances can be seen on a large screen of a TV or the like, there is an advantage in that high-level contents services can be provided to general users who are not familiar with the manipulations of PCs and small screens of monitors and thus are difficult to appreciate movies, images or photos, or the like photographed or captured by digital camcorders or cameras.
